Last post for today: My radiator warning light has gone off intermittently, sometimes immediately after startup. At Miltonian's recommendation, I unplugged both Temp sensor connections and drove the car. The light came on though not quite as frequently, so I guess I have a short somewhere. I just pulled the codes and got 1112 for the temp sensor on the 5/8 side only. Since they were unplugged, did this cause the code or does it just show that the 5/8 sensor is bad? I also found a little coolant under the O2 sensor connections. Could it be that 5/8 sensor just needs to be tightened? I don't see any coolant hoses near that area. I would have just tried tightening it but cannot get a wrench in there. The connector is in the way so I cannot use a deep socket and I can't reach it with a wrench. Thanks for your help as always.
